Hehe - yes Chuck I would have figured it out had I taken the time to stick my head under the car. Those air injector plugs had been in for maybe 5 years when that happened, I had forgotten about them. A blown exhaust gasket, cracked exhaust and blown out injector plug all sound the same. I have heard that sound a few times in my life on V8 cars with iron manifolds. It is a familiar tune. Add all that to being in a time crunch to leave town and you mess up.
I did say this was an embarrassing story aftrer all.
